About the NVIDIA GeForce RTX 3080 Ti Mobile GPU

The NVIDIA GeForce RTX 3080 Ti Mobile is a mobile graphics card that launched in Q1 2022. It is built on the Ampere GPU microarchitecture (codename GA103) and is manufactured on a 8 nm process.

Memory

The RTX 3080 Ti Mobile has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The RTX 3080 Ti Mobile includes 7,424 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 810 MHz and can dynamically boost its clock speed up to 1,260 MHz. Complementing the processing units are 232 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing. Additionally, the GPU features 232 tensor cores optimized for AI-accelerated workloads and 58 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 115 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RTX 3080 Ti Mobile has the 34th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 40.42% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon HD 6990M GPU

The AMD Radeon HD 6990M is an end-of-life mobile graphics card that released in Q3 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Blackcomb) and is manufactured on a 40 nm process.

Memory

The HD 6990M has 2 GB of GDDR5 memory, with a 900 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 115.2 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The HD 6990M includes 1,120 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 715 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 100 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The HD 6990M has the 291st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.09% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
